AI Article Synopsis

  • The article discusses the need for a new classification system for retronychia, a condition affecting nails, using recent literature as a basis.* -
  • It outlines various factors influencing retronychia, including the duration, severity, and types of nail displacement and alignment issues.* -
  • The proposed classification system consists of three categories: Acute (A), Ongoing (O), and Chronic (C), aimed at improving diagnosis and understanding of the condition.*

Article Abstract

Background: A retronychia classification system is overdue considering the most recent publications. Using the keyword "retronychia", publications with a narrative literature review were selected from PubMed/MEDLINE, EMBASE and Google Scholar, adding a few select papers.

Summary: This article proposes a theoretical pathophysiological basis for retronychia. Several factors alter the clinical picture of retronychia: length and periodicity of backward displacement, duration of disease, intensity of paronychia, presence and type of nail stacking (polymeronychia), and remodeling of the nail apparatus (elevation of the proximal nail, nail bed shortening, retroversion of the distal nail fold and acquired malalignment).

Key Messages: With these factors in mind, we propose a new classification system for retronychia: A standing for acute, O for ongoing, and C for chronic. We believe this easy system may increase the diagnostic acuity for the disease and its understanding.

The E6 and E7 proteins of the high risk human papillomaviruses (HR HPVs) play a key role in the oncogenesis associated with papillomavirus infection. Data on the variability of these proteins are limited, and the factors affecting their variability are still poorly understood. We analyzed the variability of the currently known sequences of the HPV type 16 (HPV16) E6 and E7 proteins, taking into account their geographic origin and year of sample collection, as well as the direction of their evolution in the major geographic regions of the world.

The gut microbiota is a crucial link between diet and cardiovascular disease (CVD). Using fecal metaproteomics, a method that concurrently captures human gut and microbiome proteins, we determined the crosstalk between gut microbiome, diet, gut health, and CVD. Traditional CVD risk factors (age, BMI, sex, blood pressure) explained < 10% of the proteome variance.

Article Synopsis
  • * Researchers identified and validated an AMP, named AMP1, which has broad-spectrum antibacterial activity and minimal toxicity to human cells, showing potential as a safer alternative to traditional antibiotics.
  • * The study emphasizes the effective screening of natural AMPs and highlights AMP1's ability to affect bacterial cell wall synthesis and promote wound healing, suggesting it could be a viable option for clinical use.
